Is it though? Are homophobes a protected class? Would a company be forced at the point of a lawsuit to hire a goose-stepping neo-Nazi if he or she had impeccable credentials?

Obviously I'm stretching this some, I'm not claiming that $1000 to Prop 8 === being an open Neo-Nazi. However I'm asking you consider that maybe the political views of employees do matter some, and that this is a gray area where you can't completely claim that "All political activity should be protected" or "Employers should be able to fire anyone for any belief". Maybe you should try and have a little empathy for this person's partner who was essentially prevented from starting a business because he was gay, albeit indirectly, and see why this could make someone a little bitter against people fighting to keep that status quo.
